Earlier today, Google rolled out a brand new feature for its online patent research tool: prior art search. Now, while looking at a patent, you can click a single button to pull up a host of results from Google Patents, Google Scholar, Google Books, with a bit of Google's typical search results sprinkled on top. The goal, of course, is to aid in researching whether a patent that's been filed is "new and not obvious." Which is far more complex than it sounds.
